Ran across this video. The whole manufacturing process looks pretty good except for how they seal the 2 ends. Wix,fram, denso etc all use some sort of positive seal be it a metal crimp or a sealant.
At the 13:00 mark they just staple the ends together. How can that seal? Won't dirt be able to get around the 2 ends?
